This is my code to add a picture to a worksheet. I get the picture as a byte from the database. .Net Core framework version is 2.2.104. This is an API project. In my locale, the code works well. I use the ClosedXML component 0.95.4 version as below.
[HttpPost("GetTowel")]
public IActionResult GetTowel()
{
string contentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
string fileName = "Towel Quotation.xlsx";
try
{
using (var workbook = new XLWorkbook())
{
IXLWorksheet worksheet = workbook.Worksheets.Add("Towel Quotation");
byte[] bytes = _fileService.Get(159).FileInBytes;
System.IO.Stream x = new System.IO.MemoryStream(bytes);
//the exception is throwed at this line:
**var image = worksheet.AddPicture(x).MoveTo(worksheet.Cell("P1")).Scale(1.0);**
using (var stream = new MemoryStream())
{
workbook.SaveAs(stream);
var content = stream.ToArray();
return File(content, contentType, fileName);
}
}
}
catch (Exception ex)
{
return BadRequest(ErrorResultFormatter.PrepareErrorResult("",ex.Message));
}
}
My Kubernetes server information is below:
System.drawing.common the type initializer for 'gdip' threw an exception
*FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build WORKDIR /app
COPY *.csproj Nuget.Config ./ RUN dotnet restore /property:Configuration=Release
--configfile=Nuget.Config --no-cache --force
COPY . ./temp/ WORKDIR /app/temp RUN dotnet publish -c Release -o out FROM mcr.microsoft.com/dotnet/core/aspnet:2.2 AS runtime ENV ASPNETCORE_URLS="http://+" ENV ASPNETCORE_Kestrel__Certificates__Default__Password="*****" WORKDIR /app COPY --from=build /app/temp/out ./ ENTRYPOINT ["dotnet", "blahblah.dll"]*
On the server-side, I get the exception as below: "system.drawing.common the type initializer for 'gdip' threw an exception"
I have searched many times on google. That way is suggested generally to add docker file:
RUN apt-get install libgdiplus
But this way also didn't solve my problem. Can anybody help me?
Thanks in advance.
